Giving blood to brothers in arms
Col. Troy Roberts, 11th Security Forces commander, has his temperature measured as a pre-evaluation prior to giving blood during the Armed Services Blood Bank Center’s blood donation on Joint Base Andrews, Md., Feb. 6, 2017. The ASBBC can only set up donation locations on federal installations making military members, military families and government employees the majority of donors.
